Abstract
This disclosure describes techniques for coding of header information of video blocks. In particular, the techniques of this disclosure select one of a plurality of prediction modes for use in generating a prediction block of a video block of a coding unit, the plurality of prediction modes including unidirectional prediction modes and multi-directional prediction modes that combine at least two unidirectional prediction modes. An encoding device encodes the prediction mode of the current video block based on prediction modes of one or more previously encoded video blocks of the coding unit. Likewise, a decoding unit receives encoded video data of a video block of a coding unit and decodes the encoded video data to identify one of a plurality of prediction modes for use in generating a prediction block of the video block based on prediction modes of one or more previously decoded video blocks of the coding unit.
